It may include a landmark extraction step (S213), a measurement step (S214), and a step (S215) of providing measurement results for each problem item.

The setup step (S220) is a step of establishing a treatment goal for solving a problem item, and a setup operation of producing virtual setup data so that the teeth are arranged in an ideal shape is performed.

The design step (S230) is a step of establishing a treatment plan according to the treatment goal, and may check and change the tooth arrangement process and schedule for reaching the established treatment goal. The planned treatment is made possible by designing, printing and using the orthodontic device for each procedure of each plan according to the treatment plan. Additionally, due to the characteristics of long-term orthodontic treatment, intermediate or final results can be identified, and continuous progress, treatment goal or plan modification, and treatment termination can be distinguished.

Hereinafter, the preparation step (S210) will be described later.

In the preparation step (S210), the device 1 classifies and presents information related to problem item setting, problem item solving, and problem solving plan establishment in advance. For example, problem items necessary for problem derivation, problem item reference values, landmarks, measurement information, tooth movement information required for problem solving, problem item solving procedures required for problem solving process, and orthodontic devices needed to solve component problems , and a comparison item to confirm the results.

The device 1 performs data matching (S211). In this case, the size ratio of each data (face, skeletal, dental data) may be equalized, and the data location may be reconstructed to match the patient's human body condition.

Next, the device 1 performs segmentation (S212). For example, the area required for orthodontic treatment of facial, skeletal, and dental data is divided. The divided facial region may be a labial region, the skeletal region may be a maxillary skeleton, a mandibular skeleton, and individual tooth root regions, and the oral region may be an individual tooth and a gum region.

The current patient's oral condition for orthodontic treatment, as well as the skeletal and facial related conditions, are classified according to defined items and criteria. The user can check the derived problem item and select the problem item to be solved. The selected problem item can be modified to a target value to solve the problem item by the user other than the suggested reference value.

Hereinafter, the setup step (S220) will be described later.

In the setup step (S220), the device 1 presents the tooth alignment target in an ideal form for solving the problem item, and presents the measurement result for each problem item and the difference from the current state in which the alignment target is reflected (S221). For example, a tooth arrangement reflecting the reference value of the selected problem item or the corrected target value input by the user is presented, and prediction results including related items according to the changed tooth arrangement are also presented. The user may further change the treatment goal while checking the predicted result. When the treatment goal is changed, the device 1 recalculates the correction and presents the predicted result again, and the user may establish the treatment goal by repeating the process of confirming and correcting the presented result.

Information on the root, maxilla, and mandible of the skeletal data may be detected based on the crown information of the dental data.

Then, the landmark can be detected in the preparation stage. A landmark is characteristic information of each data, and is a reference point for line segment, distance, and angle information for each item. For example, the feature points of the face data reflect information that can confirm the vertical, horizontal, and context of the face. The vertical information includes a midline, and the horizontal information includes an occlusal plane, a pupil parallel line, or a vertical perpendicular to the midline. Characteristic points of the skeletal data include tooth root, maxilla information, and mandibular bone information. The characteristic point of dental data is individual tooth information.

For example, as shown in FIG. 7 , the analysis results in the front, rear, left/right side, maxilla/mandibular occlusal plane, that is, the entire direction related to dental analysis are presented.

When each data (facial, skeletal, dental data, or tooth, gum data) is overlapped and displayed, the result can be presented by dividing the data into identifiable visual information for each data so that the data can be well checked along with the direction to be presented. For example, the result may be presented by reflecting the transparency differently for each data.
